Clumsy HENRY I-I. S ANFORD, OF MANSFIELD, OHIO.

COMBINED SOLID AND GASEOUS FUEL RANGE.

T0 (tZZ LUILOWZ it'may concern:

Be it known that I, HENRY H. SANFORD, a citizen of the United States of America, residing at Mansfield, in the county of Richland and State of Ohio, have invented certain new and useful Improvements in Com bined Solid and Gaseous Fuel Ranges, of

which the following is a specification.

This invention is applicable to a combined solid and gaseous fuel stove and relates especially to heating water through the medium of a gaseous fuel. .It is well known to those skilled in the art that means are provided for heating water in the ordinary coal or solid fuel range which is not available for use when the heat is provided through the medium. of a gaseous fuel.

While it is not a discomfort or inconvenience to heat the water 'by a heating coil through the method of solid fuel at times when the temperature is low, yet it is of considerable inconvenience and discomfort to do so when the temperature is high or abnormal.

The primary objects therefore of the present-invention are to provide a means of applying a heating water coil to a combination solid and gaseous fuel range, stove or the like, and means for heating the. coil and water through the medium of a gaseous fuel.

A. further object isto provide means for protecting the burner from debris," dust," ashes and other foreign substances during its operation and afford facilities for directing and conducting the debris dust, dirt and other foreign substances in a path thatwill direct its courseZbf travel to the ash' pan or pit. h r

A further object is to so locate the burner so as to direct and maintain the flame. of

the burner in contact with a maximum' amount of the surface of the water heating coil so as to rapidly and economically heat the water in the coil. 7 g

A further object is to provide a simple and efficient means for heating the water coil for the purpose intended that is convenient and comfortable'to be used for intensely heating the water in the coil without Specification of Letters Patent.

during times of high or abnormal temperature of the atmosphere."

Theseand other objects are attained by the mechanism illustrated in the accompanying drawing in which:

4 Figure .1 is a front elevation in perspec tive of. a part of a conventional type of stove or range showing the invention applied thereto.

Fig. 2 is a sectional view of Fig. 1 taken on the line X X.

s Fig. 3 is a side elevation of Fig. 1 showing a pocket provided on the side wall of the range to support and inclose a gaseous burner. i

In the drawings reference numeral 1 represents the top of the range and 22 a side wall thereof. A pocket 3 preferably tapered and enlarging toward the bottom is provided on the side wall of the range or the like either by forming the pocket integral with the side wall or by cutting away a portion of. the side wall and covering the opening with a member 4. The member is secured to the side wallin any Well known manner. The lining-5 which forms a side wall in the ordinary type of range or the like is cut away to provide an opening 6 into which a water heating coil 7 is inserted and preferably supported on a flange 8 made integral with the side wall. One side of the water heating coil extends into the solid fuel fire box'indicated at 9 and the other side extends into the pocket 3 as shown more clearly in Fig. 2. It will thus be' observed that while one side of the heating coil extends into the solid fuel fire box and forms part of the lining for the solid fuel fire box permitting the solid fuel to lie in contact with the water heating coil when solid fuel is being used to heat the coil that the other side of the water heating coil'extends into the pocket At a predetermined point in the lower portion of the pocket, or chamber 3, a gaseous burner 10 is secured to the member 4.

The burner is located and arranged to diffuse and radiate the heat emitting from the flame of the burner in the first instance against and in contact with the inlet pipe 11 of the heating water coil thence in regular sequence in contact with the other pipes of the heating coil, thereby directing the heat radiation and flame of the burner against a large area of the surface of the water heating coil. A deflector or protector 12 is secured to the member 4 so as to extend on an incline over the major portion of the gaseous burner to protect and guard the burner and jets 13 from foreign substances such as soot, ashes and the like from interfering with the efficient operation of the burner. V

Another function that is performed by the deflector 12 is to direct the course of travel of any foreign substance such as dust, ashes or the like to the opening 14 thence into the ash pit or pan (not shown) the location of which is indicated by numerals 15. The lining 5 is supported upon the grate rest 16 and the grate rest is preferably supported by one or more narrow brackets 17 made integralwith the member 4:.

Attention is called to the fact that the lower portion of the member 4 is formed to depend below the grate bar to provide for the space 14: between the grate restv and top of the lower part of the side wall. The space 14 provides a passageway to conduct any foreign substance into the ash pit or pan and at the same time provide a means for furnishing oxygen to the burner to mix with the gaseous fuel for combustion purposes.

Reference numeral 18 represents a gaseous fuel pipe, 19 the valve, 20 the air mixer, and 21 the outlet pipe of the water heating coil.

Immaterial alterations or changes may be made in the structure without deviating from the principle of the invention.

The arrangement and means shown in the drawings is directed to and designed for heating a water heatin coil with solid or gaseous fuel and especially adapted to be applied to a combination solid and gaseous fuel range or the like.

I claim:

1. In a heating element, a side wall provided with an extended tapered portion forming a pocket, a lining attached to the side wall, a water coil associated with the lining, a burner located in the lower portion of the pocket and so positioned as to permit the flame of the burner to contact with the lower pipe of the water coil in the first instance, means to protect the burner from foreign substances, said lining also being provided with an opening underneath the water heating coil to communicate with the extended portion of the side wall to provide oxygen for the burner and a passageway for any foreign substance to direct its course of travel into the ash pit or pan.

2. In a heating apparatus, means to provide a chamber thereon, a water coil .associated therewith, said chamber being provided with a passageway underneath the water coil, a burner located in said chamlower portion of the extended portion,

means to protect the burner from foreign substances, a grate bar, means provided on the extended portion to support the grate bar so as to leave an opening between the grate bar and the lower portion of the side wall as and for the purpose described.

4. A stove having water coils arranged in.

one wall of the lining, a burner, the adjacent side of the stove having an outstanding portion forming a pocket of increasing width from the coils in a downward direction and spaced at its bottom to provide an air inlet beneath and in communication with the burner, a deflector secured to such outstanding portion immediately above the burner and pocket outlet to the interior of the stove. V V

5. A stove having the fire pot lining thereof interrupted, a water coil arranged in such interrupted lining, a burner, a tapered pocket of increasing dimensions downwardly arranged below the plane of the stove side and spaced at its bottom to provide an air inlet beneath and in communication with the burner, said burner being arranged in the lower portion of said pocket to direct the flame to the coils, and supports for the coils provided on the tapered pocket.

6. A stove having water coils arranged in line with one wall of the fire pot lining,aa

burner, a tapered pocket of downwardly in creasing dimensions arranged beyond the plane of the stove side and spaced at itsv bottom to provide an air inlet beneath andin communication with the burner, said burner being arranged wholly in such pocket to direct the? flame 'to said coils, a downwardly inclined deflector arranged in the pocket immediately abovethe burner and supports for the coils provided on the pocket.

7. A stove having water coils in the lining thereof, the side of the stove next the coils having an outstanding portion to form a pocket, a burner located inthe lower por tion of the pocket, anda deflector arranged in the pocket immediately above the burner and inclining downwardly toward and spaced from the coils, the lower connection of the outstanding portion with the stove side providing an opening from the pocket to the interior of the stove.

In testimony whereof I aflix my signature.
